Unit 1 introduction into the human body Flashcards
Anatomy
study of body structures
Gross anatomy
study of larger structures
Regional anatomy
all anatomy in that specific region
Microscopic Anatomy
structures observed through a miscroscope
Cytology
study of cells
Hystology
study of tissues
Systemic anatomy
study of structures of major organ systems
Cell Physiology
is the study of the chemistry and physics and the function of living cells
Physiology
the study of the body functions
What are the 5 key components necessary for life
Responsiveness, growth, reproduction, movement, metabolism
Responsiveness
ability to adjust to the change in environment
Growth
increase in body size
Reproduction
formation of new organism generated by their parent organism
Movement
actions of the joints of the body and the motion of individual organs and individual cells.
Metabolism
The consumption of food and the subsequent conversion into energy
What are the two parts of metabolism
anabolism and catabolism
Anabolism
the process where smaller, simpler molecules are combined into larger, more complex substances. Requires energy
Catabolism
process where large more complex substances are broken down into smaller simpler molecules. Releases energy.
What is the largest component of the cells, blood and fluid
water
Homeostasis
steady state of the body, if we get to far away we die.
Pressure
the force exerted by a substance that is in contact with another substance.
Pathophysiology
study of the disordered physiological processes that cause, result from, or are otherwise associated with a disease or injury.
Surface anatomy
Study of general form and superficial markings
ATP (Adenosine triphosphate)
body’s main source of energy. made by oxygen.
Macro
means large, needs more, energy yielding. we gain energy by eating. ex: carbs, lipids and proteins .
Micro
small, needs smaller amounts, do not yield energy. ex: vitamins and minerals.
Temperature
maintain 98.6 or 37C
Atmospheric pressure
nitrogen and oxygen.
Atmospheric
pressure exerted by mixture of gases.
Higher the elevation
lower the pressure and harder to breathe
